Technical field
The present invention relates to a kind of Mgnetorheological hydraulic rubber spring, particularly a kind of for Vehicle Active Suspension System can be in real time automatically And of Varying Depth, become the Mgnetorheological hydraulic rubber spring control system of rigidity.
Background technique
Automotive suspension is the general name of all the power transmission connection sets between vehicle frame (or monocoque body) and the vehicle bridge (or wheel).It acts on vertical force (supporting force) on the wheel to the road surface, vertically counter-force (tractive force and power processed) and lateral reaction, and the moment that these counter-forces cause all is delivered on the vehicle frame (or monocoque body), to guarantee automobile normal running.The function of automotive suspension: 1. loading variation, in the situations such as speed of a motor vehicle variation and the turning of travelling, making wheel and axis keep correctly cooperating, guaranteeing the stability of automobile; 2. the assurance driver can effectively control and turn to the operability of maintenance vehicle traveling direction under the different kinds of roads condition; 3. to the smoothness of automobile running, impact and the destruction of travelling comfort and minimizing automobile road pavement play conclusive effect.
Automotive suspension is generally by resilient member, and vibration damper and guide mechanism form.Vibration damper makes rapidly decay of vibration.And the three plays respectively buffering, damping and leading role.
The vehicle body frequency of natural vibration that the quality of suspension rate and bearing spring supporting determines is one of important indicator that affects vehicle running smoothness.The frequency (being about 1-1.6Hz) that health moved up and down when the vertical vibration frequency that human body is accustomed to was walking.The vehicle body frequency of natural vibration should be in or as much as possible near this frequency range.When the carrying of automobile and the road surface of travelling change, substantially remain unchanged in order to make the vehicle body frequency of natural vibration, the rigidity of suspension need to be made variablely, namely suspension rate is little during empty wagons, and load is when increasing, suspension rate increases thereupon.The leading indicator of weighing automotive suspension performance quality is smoothness and the control stability of automobile running, but these two aspects are the performance requirements that mutually repel, and often can not satisfy simultaneously.How between is obtained rational balance is the problem that need to research and solve to reach best effect always.Passive suspension can only be satisfy smoothness and control stability contradiction compromise on structural design because have fixing suspension rate and damping constant, can't reach the ideal state of Suspension control.
Summary of the invention
Its purpose of the present invention just is to provide a kind of Mgnetorheological hydraulic rubber spring, can be in real time automatically And of Varying Depth, become rigidity, have the oil resistance height, characteristics such as regulation range is wide, thermal adaptability is strong, fast response time, and simple in structure, volume is small and exquisite, cost is low.
